One-Time gene infusion aims to fix inherited heart disease
NCT ID NCT05885412
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-stage trial tests a single intravenous dose of a gene therapy called RP-A601 in 9 adults with a genetic heart condition (PKP2-ACM) that causes dangerous heart rhythms and heart failure. The therapy delivers a working copy of the PKP2 gene to heart cells to restore protein function. The main goal is to check safety, but researchers will also measure changes in heart rhythm and protein levels.
